Reviews
The purpose-built S-Works Stumpjumper World Cup hardtail features a frame dedicated to its SRAM XX1 drivetrain and a full complement of top-of-the-line components. Light, minimalist, and fast.
  • SRAM XX1 11-speed rear derailleur for high-performance XC racing componentry
  • SRAM XX1 11-speed trigger for efficiency and simplicity on the trail
  • S-Works FACT carbon crankset w/ custom XX1 chainring for efficient power transfer
  • Roval Control SL 29 wheelset w/ Zero Bead Hook and 142+ spacing for greater control
  • FACT 11m carbon frame w/ World Cup Geometry and PF30 BB for efficient XC performance
  • RockShox SID World Cup fork w/ Brain damping and 90mm travel for race-ready XC performance
  • The custom color—Rocket Red—is designed to naturally age over time. It will exhibit splashes of a dark rich color when exposed to prolonged direct sunlight. This finish is deliberate and therefore not covered under the traditional warranty policy.
  • Lightweight Specialized flat, carbon handlebar for precise handling and control
  • Premium Magura MT8 hydraulic disc brakes w/ carbon master cylinder and reach adjust
  • Magura MT8 carbon brake levers are lightweight and responsive
  • Fast-rolling, 2Bliss Ready S-Works Fast Trak tires
